摘要
目前的投影显示器市场是以阴极射线管（ＣＲＴ）为主流的。但这种成熟的ＣＲＴ投影技术的未来发展将会变慢并发生演化。基于液晶的投影显示器在市场上被认可的程度正快速飞升。新技术正顺着几个前沿发展：（１）由多晶硅或单晶硅构成的有源矩阵；（２）用铁电液晶聚合物分散液晶或其它液晶模式制作的电光材料；（３）基于精密加工的换能器，如数字微镜器件（ＤＭＤ）和光栅光阀（ＧＬＶ）；（４）达到和超过ＳＸＧＡ的高分辨率显示；（５）高亮度显示。本文从换能器技术的角度来讨论投影显示器的市场和发展趋向。
Projection display in today′s market is dominated by cathode ray tubes (CRTs). Further progress in this mature CRT projector technology will be slow and evolutionary. Liquid crystal based projection displays have gained rapid acceptance in the business market. New technologies are being developed on several fronts:(1)active matrix built from polysilicon or single crystal silicon,(2)electro_optic materials using ferroelectric liquid crystal,polymer dispersed liquid crystal,polymer dispersed liquid crystals or other liquid crystal modes,(3)micromechanical_based transducers such as digital micromirror devices (DMD),and grating light valves(GLV),(4)high resolution displays to SXGA and beyond,and (5) high brightness. This article reviews the projection displays from a transducer technology perspective along with a discussion of markets and trends.
